XRDepthInformation: normDepthBufferFromNormView property

Limited availabilitySecure context

The read-only normDepthBufferFromNormView property of the XRDepthInformation interface contains the 3D geometric transform that needs to be applied when indexing into the depth buffer.

Value

An XRRigidTransform that needs to be applied when indexing into the depth buffer. The transformation that the matrix represents changes the coordinate system from normalized view coordinates to normalized depth-buffer coordinates that can then be scaled by depth buffer’s width and height to obtain the absolute depth buffer coordinates.

Examples

Use getDepthInformation() (CPU) or getDepthInformation() (WebGL) to obtain depth information. The returned objects will contain the normDepthBufferFromNormView of the depth buffer, which you can use for further calculations.

const normDepthFromNormViewMatrix =
  depthData.normDepthBufferFromNormView.matrix;
const normViewFromNormDepth =
  depthData.normDepthBufferFromNormView.inverse.matrix;
